 <code>Mutable</code> is used as a generic interface to the implementations in this package.
 <p>
 A typical use case would be to enable a primitive or string to be passed to a method and allow that method to
 effectively change the value of the primitive/string. Another use case is to store a frequently changing primitive in
 a collection (for example a total in a map) without needing to create new Integer/Long wrapper objects.</div>
